Esiste un comando terminale per dividere una cartella in due?

Ho una cartella con 80.000 file sul mio iMac G5 con Ubuntu 12.04.1 e non riesco nemmeno ad aprirlo con Nautilus perché si blocca.

Posso fare ls -ain Terminal e mi mostra tutto.

Esiste un comando terminale che potrei usare per dividerlo in due directory di dimensioni uguali (in termini di numero di file) in modo che Nautilus possa aprirne una più facile? O forse 4 cartelle?

ls -1 | sort -n | head -40000 | xargs -i mv "{}" /destination/folder/

Adatta anche head -40000alle tue esigenze/destination/folder/

Prova questo script qui sotto l'ho trovato su Linuxquestions.org

PhotosPath="/media/4GBSD/DCIM/101CANON"
SortPath="/home/angus/.imagesort"
LibraryPath="/home/angus/Photos"
CameraPath="/media/4GBSD"

rinominare questo percorso in base alle proprie esigenze
